I'm looking to buy a couple of 16g memory cards for my 7d (16gb 600X) I have a feeling that Sandisk have the best reputation and I can get those at $220 each but I see on the web another manufacturer, Wintec Filemate. They are available in 600X 32g on eBay for $109 each.
Is this the case of buyer beware?
Any advise gratefully received, Mike
